We reserved a mooring ball ahead of time on Dockwa - very easy and got a quick response. The Gloucester HM sent several very helpful emails ahead of time about the various mooring fields, our mooring assignment, complimentary launch, facilities, things to see and do, etc... These were very helpful. The Inner Harbor mooring field is tight and we were very close to the next boat (we are on a 50 ft SV). After talking with the HM, they let us move to a different mooring. That was great. Also, the pump out boat staff were very responsive - coming to our boat very shortly after we called. Launch staff were nice and we used the launch several times for sightseeing, dinner, etc.... We midget another helpful email from the HM office after we left - probably was supposed to have been sent ahead of our arrival. We emailed them back about this. We would come back.
